Miyata Team vs Koga Miyata FullPro

Hello all, looking for a bit of help on this one please. A friend has asked me about his bike, seemed pretty straightforward to start with - looks like a 1982 Miyata Team. Nothing is ever straightforward with old bikes though, the headbadge, fork decal, Tange Champion decals all belong more on a Koga Miyata FullPro.

Would there have been any mixing up of the decals between the two? So Koga Miyata's with the Team Miyata decal or the other way round? Or a FullPro with some Team Miyata decals added at a later date? Or the other way round? Or something else altogether?

The components are a mix of Shimano 600 derailleurs, Suntour Superbe chainset and brakes and other odds and sods. One of the shifter bosses has snapped off and clamp-on suntour shifters have been added. I guess it was all added at a later date.

From what Ive heard if there's a cutout on the BB like your friends, Its a Koga Pro or Pro L. Only Koga had the bottom cutouts. Decals would't have been interchanged. Id assume someone repainted/incorrectly "updated" the decals.

Can't see much of the HT badge but from the side it does look like it's a Koga. A Koga-Miyata badge will show Koga right on it.

The Miyata Pro does have the BB cutout, though.



Here's an '82 Full Pro.

Looking again I see the bike has clamp on shifters. That does not compute.

The dropouts are Shimano which only matches the Team (or aero) model in the 82 Miyata catalogue. The Pro is specíd with Suntour. Not sure if it was equivalent for Koga Miyata.

Iíll post a pic of the head badge.

The headbadge just says Miyata and made in Japan. Obviously it may not be original!

Edit - Handmade Japan

It's the Team. The bb cutout is correct. The Pro just has holes. The earlier team had "pro" in the seat stays and was spec'd with DuraAce. Your serial is 83' although could be early as it has silver wheels. If they are correct the D/A hub may have a date code on them, two letters and it can be researched to see what year and month they are. The size stamp below the serial on bottom bracket has DD after it, Dyna Drive. Those were on Team models with D/A.

Looks like someone added that headbadge, headset is incorrect and shifter boss appears broken.

I thought Koga the Dutch Co. bought Miyata in the 1990's? These were usually time trial, Triathlete bikes. With their short wheelbases, not really a bike you'd put fenders, etc. on.

FWIW the Koga Traveller (much lower model) I have hanging around has a K-M pantograph on the fork crown as opposed to the Miyata one.

Koga brochures are here. https://www.koga.com/en/service/broc...2000-1976).htm

Koga was it's own thing that partnered with Miyata to build it's specialty bikes. https://www.koga.com/en/about-koga/history

All the components have been changed. Rims are Rigida, rear hub is a Pelissier, front some flavour of Shimano I think (based on the skewer, no other markings). Given it’s found its way to the UK I would presume more likely to be a Koga but I don’t know its history or much about Koga / Miyata.

Seems like it’s a quality frame that’s been stripped at some point and maybe had headbadge and decals changed at the same point.

I was the original owner of this Team Miyata that I kept for over 20 years. It has the cut-out in the BB but different seat stay caps.

In 1980 TEAM Framesets were available

If you look at page 7 in the attached catalog, you will see this frame available.
From your listing of random parts, it is likely that this was built from a frame.
I bought one of these blue (only color available) 1980 frames and initially built it up with Campagnola parts, but in ~1993 rebuilt it with Shimano Ultegra 6500 (3x9 transmission ultraglide), Nitto bars and stem, and Thomson seatpost (in 26.8mm!)
It is still my main ride (I have a Miyata 710 as well with fenders for rainy weather...also from 1980...this was my wife's bike back then, but she has moved on).
It has the fancy crown cutouts in the BB and lugs, as well as the PRO in the seat stay caps.
I have always thought it odd that the TEAM and the PRO bikes are so similar, but with different geometries
The TEAM has the PRO in the seat stas and the PRO does NOT.
As well the TEAM came with a "Professional" decal on each fork blade and the PRO did not
...go figure

This thread is making me lust for another Team Miyata! I raced a 1986 Team Miyata back in the day. Although a very different bike than the 1082-3 model, it was a wonderful machine. A friend of mine still races his as a masters level racer.. His is a 1986 model as well. He upgraded from the previous generation back then and said the frame is much stiffer than non-spline frame. Also have a friend that bought a Pro Miyata in 1984 and still rides it. He was seriously fast and really tall, and never had issues with stiffness in the frame.
